Start by placing the rolled oats in a mixing container or mason jar. Add the cinnamon, maple syrup, Greek yogurt, and milk. These ingredients create the creamy base and bring the sweet apple-cinnamon flavor together.
Stir the ingredients thoroughly until the oats are completely coated in the milk and yogurt mixture. Proper mixing ensures every bite is creamy and evenly flavored.
If you're making multiple servings, divide the oat mixture evenly between two mason jars. This makes the recipe perfect for meal prep and easy grab-and-go breakfasts.
Cover the jars with lids and place them in the refrigerator overnight. During this time, the oats absorb the liquid and soften, creating a thick and creamy texture.
In the morning, slice or dice a fresh apple and add it on top of each jar. The fresh apples give the oats a crisp texture and natural sweetness that balances the creamy oats.
Give the oats a quick stir before eating. You can enjoy them straight from the jar or transfer them to a bowl for serving.
